Using the built-in note guide, you will quickly learn the notes on the treble side of the B-System Chromatic Button Accordion (Bayan) and be playing songs in no time! The instrument has extremely high-quality individually sampled notes from a real instrument and a very fast, responsive button board for playing melodies and chords. For even more fun, plug your iPhone into an external amplified speaker. Touch the "?" button to toggle the note names.
